Probably only for the truly adventurous, this is the biggest, non-circuitous loop you can do out at the Alligator River Wildlife Refuge. It's basically a traverse between Hwy. 64 and Hwy. 264 utilizing the dirt and gravel roads of the Refuge.

There is a 100-yard long section of flooded road deep in the interior that's a little over knee-deep and very cold in the winter. Start at the Milltail Road parking lot on Highway 64 (approx. 4 miles west of Manns Harbor.) Pedal south on Milltail Road for 9 miles or so and bear right on Alligator Road. The gravel ends and a 10-mile dirt road section begins that can be very rutted and puddled. At around 15 miles into the ride you'll arrive at the big, flooded section. On the other side of the big puddle the road turns back to gravel and then to pavement at the bombing range, eventually dumping you out on Hwy. 264 in the middle of nowhere. Turn left and pedal the long, boring 13 miles or so to the turn for Stumpy Point. At this point you can skip the 6-mile out-and-back to the Stumpy Point Store but it's the only "civilization" on the route and definitely adds to the charm.

After leaving Stumpy Point, go north (east) on Hwy. 264 for a couple miles and turn left, back into the refuge gravel roads. After a mile or so turn right on Long Curve Road and follow that until jogging over to Bear Road. Skirt the gate after Bear Road and ride the bumpy grass-patch perimeter road around to the end of the asphalt nature trail. The trail leads immediately back to the parking lot. This is a big one! You'll be out in the boonies in the company of bear, snakes and alligators.
